EEG-based control for human-computer interaction

An interface whereby brain responses can control machines has been developed by the Armstrong Laboratory. This EEG-based control uses the magnitude of the steady-state visual evoked response (SSVER) as a control signal. The SSVER is identified and monitored using non-invasive scalp electrodes and advanced signal processing technology. With biofeedback, users learn to increase or decrease the magnitude of the VSYER to an evoking stimulus. These responses are translated into commands that control the operation of a physical device or computer program. After further development this innovative interface could revolutionize human interaction with complex systems.
